3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Grinding Disc 1169F was developed to make grinding processes faster, more consistent, and more economical. It is designed for professional users who expect both high material removal rates and reliable surface quality—regardless of the duration of use.

This is made possible by the newly designed 3M precision-shaped grain with rounded side geometry. During operation, the grain splits in a controlled manner, continuously exposing new, sharp cutting edges. As a result, the disc cuts efficiently through the material rather than pushing it aside, maintaining consistently high performance throughout its entire service life.

The flaps are designed to wear down in a controlled manner, continuously exposing fresh abrasive material. This ensures uniform material removal while reducing heat generation—a clear advantage when working with stainless steel, structural steel, and heat-sensitive alloys.

Thanks to its flexible design, the flap disc adapts perfectly to edges, radii, and contours. It covers numerous work steps, from powerful weld bead grinding to clean transitions and finishing work. In many applications, this eliminates the need for an additional tool change, saving time and reducing process costs.
